OHRISTOPH. RIESSNER, OF NEW YORK, N. Y., ASSIGNOR TO G. RIESSNER & 00.,OF SAME PLACE.

SHEET-METAL-WIRING MACHINE.

SPECIFICATION forming part of Letters Patent No. 251,289, dated December20, 1881.

Application filed November 14, 1881.

To all whom it may concern Be it known that I, OHRIsroPH. RIESSNER, ofNewYork, in the county of New York and State of New York, have inventedcertain new and useful Improvements in Sheet-Metal-Wiring Machines; andI do hereby declarethat the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,and to the letters of reference marked thereon,which form part of thisspecification.

This invention consists in the combination, with the well-known tinnerswiring-machine, of a raised rib or guide formed on or suitably appliedto the upper surface of the bed-plate, and provided with recess toreceive the ears on the wires which are to be inclosed in the turnededges of the blanks. My object is to insert the wires into the edges ofthe tin blanks at one operation, when said wires are provided with theloops or bends which form the bail-ears for the cans or bucketsintowhichthe wired blanks are formed.

In the annexed drawings, Figure l is a side elevation of a tinnerswiring-machine having my improvements applied to it. Fig. 2 is a topview with part of the parallel rail broken away to expose the recessedrib on the top of the bed-plate. Fig. 3 is an end view with a portion ofthe pedestal of the machine broken away. Fig. 4 shows a wire with earsformed on it. Fig. 5 shows a blank with the wire inserted into its edge.Fig. 6 is a vertical crosssection through Fig. 2 in the plane y. Fig. 7is a similar section taken in the plane 2.

Similar letters of reference indicate correspondin g parts. 7

A designates a horizontal arm, which is rigid onafixed pedestal, and Ais a narrow flatfaeed rib for elevation on the top of the arm orbedplate. This rib A extends nearly the entire length of the arm and isarranged in the middle of the width of it, as shown in Figs. 2, 3, 6,and 7. It is constructed with parallel edges perpendicular to thesurface of the bed-plate, and in the front edge of this rib A, I formnotches (No model.)

or recesses a, which are intended for receiving the loops or ears 9 onthe wire G during the operation of wiring a blank, H, as shown in Figs.6 and 7. For the purpose of properly supporting the blank H during thewiring operation I use two horizontal rests, a a, which are rigidlysecured to the arm A, and project out at right angles therefrom, asshown in the drawings. The tops of these blank-rests a a are level withthe base of the rib A, as clearly shown in Figs. 3, 6, and 7.

G designates a carriage, and D a flanged wiring-wheel, which is appliedto it so as to roll over the wire and edge of the blank H, as shown inFig. 7, and bend this edge neatly about the wire. This wheel D turns theedge of the blank around the wire against the front edge of the rib A,while the opposite edge of the rib serves as a guide for theflangedwheel.

The wheel D is held down hard upon the work by means of a horizontalbar, B, which is rigid with the standard or pedestal and. which isparallel to the surface of the bed-plate A. Against the bottom edge ofthis bar B a small anti-friction roller, 73, bears, as indicated indotted lines, Fig. 1.

The carriage O is moved back and forward over the bed-plate A by meansof a rack, E, with the teeth of which a pinion, F, on the short shaft ofa crank engages.

Having described my invention, I claim- 1. The combination, with the armor bedplate A of a tinners wiring machine, of the raised rib A",recessed at a a, substantiallyin the manner and for the purposes setforth.

2. The combination of the blank-rests a, the bed-plate A, and therecessed rib, substantially as and for the purpose described.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.
